Description
The renormalization group invariant, to all orders in perturbation theory, relations among parameters consist the basis of the reduction of couplings concept. N=1 supersymmetric Grand Unified Theories can use the above concept, and even become finite at all loops. In our work we analyse four phenomenologically favoured models: a minimal version of the N=1 SU(5), a finite N=1 SU(5), a N=1 finite SU(3)xSU(3)xSU(3) model and a reduced version of the MSSM. A relevant update in the phenomenological evaluation has been the improved light Higgs-boson mass prediction as provided by the latest version of FeynHiggs. All four models predict relatively heavy supersymmetric spectra that start just below or above the TeV scale.
